Cook the mushrooms in a heated skillet for about 5 minutes until slightly golden brown. Mix the smoked paprika with the soy sauce, stir into the mushrooms.
Add all the omelette ingredients to a blender and blend until smooth.
In a separate lightly oiled heated skillet, add 1/4 of the mushroom mixture, and 1/4 of the omelette mixture. Fry for 5-8 minutes on medium until golden brown. Flip and fry the other side for a few more minutes.
