Well, here is my attempt at yak folk mystics (which replace the yak folk sorcerer's in the third module). Special thanks to Starfox for suggesting the yak folk's theme.

Initiative +5 Senses Perception +5; darkvision
Splendid Isolation (psychic) aura 3; each enemy within the aura must spend 1 extra square of movement for each square it moves closer to the yak folk. If the yak folk takes psychic damage, the aura is negated until the end of the yak folk’s next turn.

The push of the four mountains power and the aura will be common across all yak folk. The mystic specific powers are basically reskinned sorcerer powers.
Building off of the yak folk mystic, I converted Arghakot Annapuma, a yak folk who figures prominently in the series.
