Whisk the almond or soy milk together with the apple cider vinegar. Let sit for 5 to 10 minutes, and then combine the clabbered milk with the oats in a medium bowl. Let sit for 10 minutes.
In a small bowl, whisk together ¼ cup warm water, almond butter, and maple syrup to make the almond butter drizzle. Whisk until smooth. Set aside until the pancakes are ready.
In a large bowl, sift together the flour, baking powder, baking soda, and sea salt.
Mix together the remaining 3 tablespoons of warm water and the ground flaxseeds.
Add the milk–oat mixture, the flax mixture, and the vanilla to the flour mixture, stirring until just combined.
Heat a large griddle over medium-high heat. Spoon ½ cup of the batter onto the griddle and cook until the edges look dry, about 2 or 3 minutes. Flip and cook for 1 to 2 minutes on the other side. Repeat with the remaining batter. Cover the pancakes so they stay hot while the rest are cooking.
Serve drizzled with the almond butter sauce and garnished with fresh fruit.
