There are a couple of problems that Nerd of the Rings points out with saying he's a valar or a maiar. 1. Tom claims to be older than the world and the eldest, but the maiar enter the world after it exists. The first being sent to enter the world (by Eru) is Melchor. I can resolve these issues by identifying Bombadil as an avatar of Melchor.
I believe that Tolkien is in his Silmarillion addressing the problem of the existence of evil in Eru's creation. Why must evil exist? Eru tells Melchor that Melchor must descend into the creation to see the effects of the disharmony that he has made, but this seems paradoxical since Melchor goes into the world and begins to wreak havoc according to his own desires and not as someone watching them.
I think Tom Bombadil is an avatar of Melchor, but a part of Melchor which must watch the effects of the disharmony. Eru has told Melchor that he must observe the impact of his disharmony. Bombadil has said he is Eldest, thus identifying with Melchor who is the eldest. Bombadil is stronger than anyone yet unable to challenge Melchor nor Melchor to challenge him. They have a strange dissociation. They are like twins, but one is a watcher and the other a doer.
In addition it is said in the books that one day Melchor will be reunited with Eru. Bombadil as an avatar of Melchor is a good picture of this working. Bombadil is there to observer the effects of disharmony.
