We are preparing to put new sheet vinyl down in a kitchen. We tore out the old subfloor and replaced it with new plywood. Is there any benefit to putting tar paper down between the floor decking and plywood subfloor ?

Yes its an additional vapor barrier and could prevent underlayment from warping. In a bathroom its always a good idea to do to keep moisture away from subfloor.
