It honestly just depends on what feeling you want to portray with your deities. Are they vengeful, narcissistic entities full of self-love, wrath and arrogance? Groveling, material sacrifices and devotion is the way to go. Are they benevolent, altruistic powers, devoid of any need of petty sacrifices? They would still love for you to perpetuate their ideals and ideas. Are they proto-deities with a simplistic focus on a portfolio? Seeds for the farm god! Kindling for the fire god! Is it a monotheistic cult that believes their god above all? Maybe sacrifice some non-believers.
