In yin and yang,
Yin means right, shade, inside, moon, female.
Yang means left, brightness, outside, sun, male.
Sun and moon are very common representations for yin and yang. So how about using poka mun for right and poka suno for left?
Even though this is from a specific culture, what would be universal other than asymmetrical body parts and the fact that most people are right handed?
For north south east and west you could try saying the top direction, bottom, right, left. North is often associated with being up, south is associated with being down, and so on.
