Faerun or your home brew that has bog standard gods. The gods are granting prayers to high level clerics. They are on a plane in their castle.
But what are they doing day to day? I understand time is different but how do you envision it?
I think of stock D&D gods a lot like fiend lords or stories about Greek and Norse Gods.
They have personal actions they engage in, super hero myth type actions. Hermes goes on a mission to rescue one of Zeus's paramours and uses his wand of sleep to put the hundred eyed giant to sleep one eye at a time. Malar the evil hunting god might come up with a plan to stalk Nobanion the noble lion god to consume his divine essence and gain more divine power, similar to how he tried in the Time of Troubles.
They might have duties they regularly engage in, Hermes brings messages from Zeus to mortals, he is a psychopomp, etc. Kelemvor judges the dead in certain circumstances.
They have plots in the planes and in the mortal world that they enact through their divine agents in the planes and their mortal followers in the world so I see them leading their forces and dealing with their agents like a king or CEO with a lot of delegation.
I think of stock D&D gods as being both individuals and connected to their divine aspect. So while Thor might be present in every storm, he is also simultaneously an individual who can go into Jotunheim to fight giants without stripping the world of storms.
I mostly view clerics as getting their power from divine power, not really the traditional D&D view of gods giving out individual spells directly. So I conceive of D&D Thor as being a lot like mythical Thor done as a D&D monster/character/being and not necessarily a clerical magic casting being from being a god. I am fine with D&D god Thor being a giant slayer with a thunder smacking returning hammer but incapable of casting spirit guardians or speak with the dead and such if you encounter him, even though his clerics can cast those spells drawing on his divine power.
