Preheat the oven to 200°F Put the soy milk and water into a small bowl and stir until well combined.
Whisk the dry ingredients together in a large bowl. Add the wet and stir to combine, using as few strokes as possible so you do not overmix the batter.
Let sit for 5 minutes to allow the batter to thicken. Lightly oil a frying pan over medium heat.
Using a measuring cup, pour 1/4 cup dollops of batter onto the pan . Cook until pancakes are bubbly on top and the edges are slightly dry, 2 to 3 minutes. Trun and cook until the pancakes are light brown on the bottom, 2 to 3 more minutes.
Transfer finished pancakes to a baking sheet and keep warm in the oven while you cook the rest. Oil the pan before each new batch.
