Well first, do you want a FAA PVT SEL or glider certificate? FAR 61.109 lists the aeronautical experience required for a PVT certificate. You would have to go through your logbook and see what you have a training record of and see how that meshes with the FAA requirements. As rudestuff said, there is a 3 hour requirement of test prep by a FAA CFI that you'll need. If you're going for the glider rating the requirement is 3 instructional flights with a CFI-G. Those are minimums. Everything else will be hit and miss. There is a requirement for 3 hours of night training for the SEL in a SEL airplane. Say you have 5 hours night training - that square is filled. But, of those 3 hours of FAA night training there has to be a 100 mile X-C flight. No night X-C training logged? You'll have to head out 51 miles with an instructor. Same thing for hood work, solo X-C time, controlled field landings, etc.
