In a medium size mixing bowl, combine almond milk and lemon juice. Whisk well and set aside for few minutes to curdle.
To the milk mixture, add oil, vanilla, sugar, maple syrup and pumpkin puree. Whisk well to combine.
Sift in the flour, baking powder, baking soda, pumpkin pie spice and salt. Mix until just combined. Set aside for 10 minutes.
In the mean time, heat a griddle on medium heat.
When ready to make pancakes, spray the griddle lightly with cooking spray. Pour about ¼cup of batter for each pancake. Cook on medium heat until bubbles start to form around the edges, takes about 1~2 minutes. Gently flip and cook on the other side for another 1~2 minutes.
Repeat with the remaining batter. Serve immediately or keep them warm in a 200°F oven.
