Well technically, wood release is turning the user's chakra into the source of life for the plants to use as a medium for them to grow. That's why I personally think it's attributed to his whole Asura chakra/Yang/life force thing. Yeah but Yamato's wooden planks aren't living, so wood release can be used without yang but is weaker.

Actually, Yamato can he's used techniques like his nativity of a sea of trees technique. He just possesses a weaker variant of Hashirama's wood release in general. It has nothing to do with possessing his yang chakra.
