Vecna isn't a god in any book that I'm aware of*. If he were, he would presumably have reclaimed his eye and his hand.
* Stuff invented by later writers at a different company doesn't count.
You can't just say that everything after 2e isn't D&D, because a different company created it. Vecna became a god in D&D.
