Mix ground flaxseed (you can mix them in a blender optionally) with about 50-70ml oatmilk and add a generous amount of lemon juice. Put it aside so it gets thick, this is the egg & buttermilk replacement
Conbine flour, baking powder & soda, sugar and salt. Then slowly add the flaxseed-oatmilk mixture, oatmilk and oil. Don't overwhisk it so you get fluffier pancakes
Cook the pancakes in your desired size in a pan with some coconut oil until the top gets bubbly. Flip and cook the other side for 1-2 more minutes. Serve with toppings of your choice like jam, maple syrup and butter. Enjoy!
