Add soy milk and blueberries and stir gently until "just mixed".
If the batter is too thick or runny, add more soy milk or flour accordingly.
It should be a "pancakey" consistency.
Pour batter in small amounts to a warm, un-oiled, non-stick frying pan on medium heat.
When edges start to pull away from the bottom of the pan and a few bubbles form on the tops, lift up a little and check to see if the pancake is turning a light golden brown.
When they are, flip the pancakes over.
After a few minutes, carefully make a little slit in one to see if it is cooked all the way through, and check that the second side has become a light golden brown colour.
