The best I can suggest is checking out the PVC moldings at a big box store. I've seen some variations on panel joints and T moldings and such, I think. You might also have success applying eternabond tape over the seams once you've completely finished the plywood, though I think it would look rather poor.
On the whole, this scheme of covering sounds somewhat problematic to me, for what it's worth. Typical current practice is to have a seamless sheet of flexible filon or similar (a sort of fiberglass laminate, I think) over whatever substrate is used, or else interlocking corrugated aluminum siding strips. Maybe I just lack some sense of adventure or don't have enough faith in unconventional approaches.
