Does Yahweh exist in Planescape? If so, does he (HE in the most abstract of the sense) cling to any particular religion, or is he a mix of Christian/Jewish/Islamic views, or is he separate from these views and some kind of other idea? I always believed he would be worshiped in sects. What's his divine rank, if any? Is he perhaps an overpower, maybe an overpower of overpowers? Where plane does he reside in, if it's at all in this multiverse. Alignment? Philosophies? Dogma? Who are his proxies? Does he even have need for them?
On a crunchier note, what would his domains be? Can he have Favored Souls?

For purposes of enjoying the game, the God of the Abrahamic Tradition hasn't been canonically treated in Planescape. The closest place we've seen a parallel is the Overgod A.O. and the High God of Dragonlance. Given A.O. seems to stand for "Alpha and the Omega" while The High God was artistically intended to be the God of Israel (as keeping with the authors RL faiths), it would seem that YVHS probably is an Overpower in Planescape.
However, a strong argument could be made that the "Great Unknown" of the Athar is, ironically, also a statement on monotheism as opposed to just being the atheists/agnostics faction (Which is a really weird idea when you get down to it: Atheists, Agnostics, Deists, Jews, Christians, and Followers of Islam get together in Sigil to discuss philosophy). Strangely, for a God whose undefinable, the Greater Unknown seems to be an explicitly LG Deity.
That's certainly the alignment of all of his priests in Planescape.
This is keeping with the interpretations of how God is supposed to be by most RL scholars (though I've seen plenty of "Jesus was Neutral Good" alignment threads).
If you wanted to reduce YVHS to the status of pantheon Head. I would make the character very similar to Destiny from Sandman in some respects or In Nomine's Yves. YVHS being a LG Greater God that is the only god of a Pantheon that is served by extraordinarily powerful Archangels that have equal power to the Demon Princes. He is a dire enemy of Asmodeus and dwells on Mount Celestia. This nicely bookending the Christian theme of the Plane and Archons without getting too religiony.
Jewish Lore incorporated. YVHS's proxies would be the Prophets of Israel with a special emphasis on Moses and Elijah as the most explicitly "these folk have the power of God behind them."
In D&D terms, you could make a strong case of Jesus being an avatar.
