If this weren't E6, maybe he'd go into Dark Reflections just for the name…

Spoiler: Level 1
As a Shadowcaster, Smoke can only use Carpet of Shadow once per day. However, he's very sneaky with up to +20 or more on Hide, and solid Move Silently supplemented by Silence. Dissolving Spittle gives him a source of consistent damage output in a fight without having to commit, and he can add to it further with alchemical devices.

Spoiler: Level 3
Smoke is a bit more consistent now, with a second combat power in Black Fire. He can relatively easily hit DC20 on his Craft checks now, which opens up a lot of control options like Smokesticks, Eggshell Grenades, Flashtubes and Alchemist's Fire. Bend Perspective and a Dark Bat familiar gives Smoke a ton of good scouting options, both for extending vision, and blindsense + a second scouting buddy with similarly excellent stealth abilities.

Spoiler: Level 6
Taking Clinging Darkness twice, with Favoured Mystery, gives Smoke 4 uses per day of the effect, which lets him actually contribute well to battlefield control as well as just being a sneaky guy. He's also able to hit DC25 Alchemy craft now, just with Masterwork Tools and an Aid Another from his Familiar, giving him access to more tools like Sleep Gas, Thunderstones and Tanglefoot Bags.

Spoiler: E2
With essentia available to invest into Dissolving Spittle, and share it with his familiar, Smoke now contributes a lot more heavily to the damage game rather than focusing on control, with two 3d6 acid ranged touch attacks each round and good Dex to hit with.

Spoiler: E10
Improved Familiar lets Smoke upgrade from a standard Dark Bat to a Dark Night Hunter Bat. This has the major advantage of being Medium, which means he can use it as a mount. With a 60ft. Perfect fly speed and fantastic stealth skills, the pair can appear and disappear from the shadows and throw stuff at enemies. Grenadier and Mad Alchemist let Smoke disrupt the opposition more thoroughly, particularly spellcasters - the entangling penalties make it harder to escape from his 6/day Clinging Darkness, which in turn allows Smoke to apply more effects like Black Fire. Kruthik Claws give Smoke and his mount an extra +8 on Hide and MS if they're not in combat, and Cloak of Deception lets Smoke re-hide if he gets spotted, or get out of trouble if he's caught somehow. Unfortunately he can't benefit from Darkstalker because he can't apply it to his mount, but he can bob into range, throw stuff, and back off again (squares are only AC5, so the -4 for attacking while his mount runs is fine) to stay out of range of anyone who spots him.
