From my Tome of House Rules v1.54
A note on symbols:
* designates an element I am not happy with and requires further work
** designates a change that is largely based on flavor and setting, instead of balance reasons.
-Natural Spell is banned.
-You may take a ‘skill feat’ that gives +2 to two skill checks and apply it to a skill set instead of two separate skills. Alternately, you may select another type of skill check along the same theme. You gain the benefit for that type of check as well. This other skill may not be Spellcraft, Use Magic-Device or Concentration.
-Combat Casting grants a +5 bonus.
-Combat Expertise allows the subtraction of any value from attacks rolls, limited only by BAB.
-Combat Reflexes allows you to make Attacks-of-Opportunity while flat-footed (but you must be aware of your opponent). This does not make you not flat-footed; it is not Uncanny Dodge.
-Dodge works on any opponent, as long as you are aware of them prior to the attack. For supporting Feats or abilities that work off of Dodge, you must still declare an opponent for those abilities.
-*Endurance Grants +2 HP and allows you to move your normal speed despite encumbrance, in addition to normal benefits. It now has “Con 13+” as a prerequisite.

-Weapon Focus grants +2 to hit with the selected weapon.
-Weapon Specialization grants +3 damage with the selected weapon.
-Greater Weapon Focus grants a further +2 to hit with the selected weapon, +4 to defensive Sunder or Disarm rolls involving the weapon and the ability to take 10 on attack rolls involving the weapon.
-Greater Weapon Specialization grants a further +3 damage with the selected weapon and doubles the weapon damage dice (1d8 becomes 2d8, 2d6 becomes 4d6, etc). Furthermore, you automatically succeed at critical confirmation rolls with the selected weapon.
-Divine Metamagic is Banned.
-Arcane Disciple is Banned.
-Lion’s Pounce has the added prerequisite of “two other Wild feats”
-Reach Spell only takes up a slot 1 level higher.
-**Sanctify Relic is removed.
-Serpent’s Venom lasts for 1 round (feat doesn’t specify a duration).
-Spontaneous Healer and Wounder are removed.
-True Believer grants you +4 to saves to avoid doing something contrary to your faith instead of the listed benefits. (generally something that would threaten to make you lose cleric/paladin standing)
-**Faith Feats will not be used.
All feats that grant spellcasting ability (such as communicator) are removed from normal play. They may be allowed in very specific circumstances or character concepts.
Mage Slayer and its chain cannot reduce your caster level below 1 (that is to say, if you are a 1st-level caster with 3 Mage Slayer feats, your caster level is still 1).
-Born of the Three Thunders: Uses a spell slot 1 level higher.

For instance, at level 6, it would allow you to treat a skill you had no ranks in (such as Decipher Script) as having 2 ranks in that skill.
-Leap Attack: As part of a charge, make a DC 15 Jump check to spend 10 feat of your movement in the air. If you are only moving 10 feet total in your charge, increase the Jump DC to 20. The initial strike of your charge gains a total of +4 to hit and you deal an amount of additional damage equal to your strength modifier. However, you suffer a -4 penalty to AC. These effects replace the normal benefits and drawbacks from charging.
-Natural Bond may only be used to offset multiclassing penalties, not the adjustment to effective level imposed by having a more powerful animal companion.
-Using Subsonics increases your Perform check DC by 5.

-Kiai Shout is removed.
-Monkey Grip now reads “You may wield weapons as if you were one size category larger. Thus, you do not suffer the normal -2 penalty to attack when wielding oversized weapons.” and nothing further.
-Phalanx Fighting does not require you to use a light weapon. If you are using a tower shield instead of a heavy shield, the bonuses the feat grants double to +2 static and +4 (with +2 to Reflex saves) when near another Phalanx Fighter, for a total bonus of +6.

-*Raptor School: You may set your Eagle’s Swoop DC at 35 or higher, granting +2 more to damage each time (thus +6 at DC 35).

Prerequisites: BAB 10+, Armor Specialization, proficient with all types of armor.
Benefit: The AC granted by any armor you wear is increased by 2 and the Armor Check Penalty is reduced by 4. Furthermore, you gain Damage Reduction based on how heavy your armor is. Light armor grants DR 2/-, Medium armor grants DR 5/-, Heavy Armor grants DR 10/-. The DR granted by this feat does not stack with that granted by Armor Specialization.
Defensive Feint [General]
Benefit: When a character successfully feints an opponent, he or she may elect to forego the opponent becoming flat-footed against the next attack in favour of gaining either a +4 dodge bonus to AC or partial (20%) concealment against that opponent for the duration of the following round.
Improved Whirlwind Attack [General]
Prerequisites: Dex 13+, Int 13+, Combat Expertise, Dodge, Mobility, Spring Attack, Whirlwind Attack, BAB 9+
Benefit: You may use the Whirlwind Attack feat as a standard action.
Master Whirlwind Attack:
Prerequisites: Dex 13+, Int 13+, Combat Expertise, Dodge, Mobility, Spring Attack, Great Cleave, Whirlwind Attack, Improved Whirlwind Attack, BAB 11+
Benefit: The Whirlwind Attack feat may be used in conjunction with Great Cleave.
Prerequisites: BAB 5+, Improved Sunder
Benefit: As a standard action, you may attempt to make a crippling attack. If your attack deals 10 or more damage, your target’s move speed is reduced to half. Your attack may be a melee attack or a ranged attack within 30 feet.
This reduction lasts until the subject heals an amount of damage equal to the original attack.
Prerequisites: Innate Resistance 4, Con 13+
Benefit: Your Innate Resistance value improves by 4.
Special: You may take this feat multiple times, its effects stack.
Prerequisites: Innate Resistance 14, Con 15+
Benefit: Spellcasters must check twice to overcome your Innate Resistance, succeeding both times in order to effect you with a spell. If you have an ability that is bolstered passively by IR, it is also subject to this benefit.
Prerequisite: Innate Resistance 11, Con 15+
Benefit: You gain +2 to all saves versus spells and spell-like effects.
Precision Strike [General]
Prerequisites: BAB 1+, Weapon Finesse
Benefit: On your action, before making attack rolls for a round, you may choose to subtract a number from all melee attack rolls and add that number to all melee damage rolls. This number may not exceed your base attack bonus. You must use a weapon that benefits from Weapon Finesse with this feat. The penalties to attack and bonuses to damage last until your next turn. Targets immune to precision damage (such as undead) are likewise immune to this effect.
Unlike Power Attack, the kind of weapon and how you wield it is irrelevant to the functioning of this feat; the only requirement being that you use a weapon you have taken Weapon Finesse for.
This feat cannot be used in conjunction with Power Attack or Called Shot.
Called Shot [General]
Prerequisites: BAB 1+, Point Blank Shot, Precise Shot.
Benefit: On your action, before making an attack roll, you may choose to subtract a number from your ranged attack rolls and add that number to your ranged damage rolls. This number may not exceed your base attack bonus. Targets immune to precision damage (such as undead) are likewise immune to this effect.
Your target must be within 30ft to benefit from this effect.
This feat cannot be used in conjunction with Power Attack or Precision Strike.
Pin Down [General]
Prerequisites: BAB 6+, Point Blank Shot, Precise Shot.
Benefit: As a full-round action, you may make a single ranged attack with a bow, light or heavy crossbow or medium-sized or larger thrown weapon against a ground based target within 60ft. If your attack hits, your opponent must make a Fortitude save (DC = 10 + damage dealt) or be pinned immobile by your attack, unable to move from that spot. Your opponents may still attack and defend themselves normally and this feat does not work on opponents more then two size categories larger then yourself.
This effect may be removed be a DC 20 heal check requiring a full-round action or by magical healing equal to the original damage of the attack. Otherwise it ends in 3 rounds as the weapon works itself free.
Alternately, the affected individual may attempt a DC 15 Strength check as a move-equivalent action to pull the weapon free. However, doing so results in 1d8 damage to the individual and reduces their movement by half (DC 15 heal check to remove this penalty, or magically healing the damage caused by pulling the weapon loose).
If an opponent is afflicted by more then one Pin Down effect, increase all DCs by 5 for each additional active effect.
Charge Breaker [General]
Prerequisite: Weapon Focus and Weapon Specialization (any weapon that does additional damage to a charging opponent, such as a longspear), BAB 3+.
Benefit: When you ready a weapon against a charge, you deal double damage (or triple damage with a spear). Furthermore, you gain +4 to hit a charging opponent.

Prerequisites: Ability to cast Dispel Magic or Greater Dispel Magic, Spell Focus (abjuration), Spellcraft 5 ranks, Know (arcane) 5 ranks.
Benefit: Add 4 to your caster level check when you cast Dispel Magic or Greater Dispel Magic. Gain +2 to Spellcraft or knowledge (arcane) checks to identify an active spell or magical effect.

Linguistic Mastery [General]
Prerequisites: Mastery (rank 5) of three languages, Linguistic Specialization, Int 15+.
Benefit: Gain a +4 competence bonus on all language-dependant skills. This bonus stacks with that granted by Mastering a language.
Furthermore, Speak Language is always a class skill for you, and you may purchase Speak Language ranks at half the normal cost.
Finally, you may cast Comprehend Languages at will.
Quicken Skill [General]
Select a number of skills equal to 3 + character's Int modifier.
Prerequisite: 1 rank into each selected skill.
Benefit: The character can perform the selected skills in half the time if it requires more than a full-round action to perform. Skill uses requiring a full-round action are reduced to standard actions while skills requiring standard actions are reduced to move actions. Skill uses requiring move actions cannot be quickened.
Special: This feat can be taken multiple times. Its effects do not stack. Each time it is taken, it applies to a new set of skills.
*Disable Magic (rogue special ability)
Benefit: You can disable or bypass locks, traps or other obstacles or ongoing spell-effects made by magic using special dispel dust applied skilfully. The DC to Disable Device any particular effect is 25 + spell level. This removes the magic effect from as much as a 10ft area. You can use this ability against any ongoing magical effect that would be effected by Dispel Magic.
Poison Use (rogue special ability)
Benefit: You gain Safe Poison Use (as assassin).
