What did Master Yi even teach Wukong
"Alright now focus your mind so you can't be slowed"
"I'll try spinning, that's a good trick!"

He taught him how to fight. It's a bit weird and I don't know if the story is still the same, but from what I remember Yi was fiercely training in a fit of rage by himself after Singed destroyed his village and Wukong would try to copy him. Yi noticed this and decided to make him his pupil.
You're right, it's not really a fighting technique, it's a mindset. Have you read his color story, Fast and Dumb? It shows Yi's approach and Wukongs.
