Do you want them to be like the Greek Gods? Where they're more like constant, unchanging forces that exist more as obstacles for the heroes or driving force behind conflicts rather than fully realized characters. For example, there are dozens of myths about Zeus's bastard children and Hera trying to kill them, but Zeus and Hera are essentially the same in all those stories. They never learn from their mistakes, they don't try to correct their flaws, they never really change.
Or do you want them to be more nuanced and deep like the ones in a lot of modern day fantasies like Dungeons and Dragons? Where they're more aware of their own flaws, have some common sense, and are somewhat savvy about what they are. For example, like how Bhaal and Myrkul were aware of their own weaknesses and they knew about the loopholes in the divine rules so they try to game the system.
Or do you want some other kind of gods?
