Add the soy milk and lemon juice mixture to the stand mixer along with oil, cane sugar, baking soda, vanilla and salt. Mix until smooth and incorporated.
Sift in cake flour and matcha powder and mix again until smooth. Turn the stand mixer off.
Add in 1 cup of the whipped aquafaba mixture and gently fold it into the batter using a spatula.
Transfer the mixture into your lined baking pan and bake in the oven for 30 to 40 minutes, or until a toothpick comes out clean. Let the cake cool for at least an hour.
Using a chopstick or fork, pierce holes into the cake.
