Okay, so Martial arts, preferably no weapons, preferably minimal spells. From my look through OA, everything there is armed with blades or spells. That pretty much just leaves the monk.
OA Shaman would seem to have a strong connection in regards to your guardian spirits, but it is predominantly a ninth level divine spellcaster.
If willing to take up a weapon, either swordsage or Samurai could fit the bill for a eastern style martial arts oriented approach.
If not, then I guess it is back to monk, unless there's another base class that centers around unarmed fighting, I'm drawing a blank at present. What do you think?
