Soak the ground flax seed in the water in a small bowl. Set aside.
Whisk together the flour, sugar, baking powder, and salt.
Add the almond milk, vegetable oil, vanilla extract, lemon juice, and flax seed/water solution. Whisk together until smooth.
Heat a griddle to medium high heat. Spray lightly with non stick cooking spray.
Spoon 1/4 cup batter onto griddle for each pancake. Cook pancakes on first side until edges appear dry, flip and cook for 1-2 minutes on the other side. Serve immediately.
