This doesn't fit your framework, but maybe you can get an idea from it.

Generally, gods in fantasy games are either the human sort of the fruit basket because they start from humanocentric values and then become more extreme, so you get things like archetypes, whatever people care about a lot, etc.

What if instead you start by assuming that the gods are completely external and completely predate humanity, including even basic things about what it means to be human. Instead, they are there because they are necessary and are doing some task according to their own motives. E.g. 'we must create a world and fill it with life, but let us not make it in our own image - let us make it in the image of what we need'.

So instead of the usual bickering, god-vs-god opposed pantheon you have a pantheon who all work together (perhaps barring minor disagreements, but nothing like an alignment war) towards a goal that is incomprehensible (or at least, unobvious) to mortals. If one of them is called the god of rain, it is because his job somehow involves rain from time to time, not because he thinks rain is neat and embodies the concept.

Because the goal of the gods may not align with mankind, you don't get a 'perfect world' where everyone is happy because the gods agree and use omnipotence to make everyone happy. Instead you get a world where sure, there may be occasional divine intervention or aid, but there is a true ineffability to the gods and they have no reason to be loyal to their worshippers unless it aligns with their true purpose.
