Preheat your oven to 425F and cook your hash browns according to the package instructions.
In a bowl, combine soy sauce and maple syrup. Add the sliced tempeh and mix to evenly coat. Set aside.
In a small bowl, combine the mayo and 2 tbsp sriracha and set aside.
Toast the English muffins and cook the vegan egg patties in a little olive oil in a pan over medium heat. Add the sliced cheese and a splash of water; cover with a lid. The steam will help melt the cheese to perfection.
In a separate pan, cook the marinated tempeh over medium heat with 1 tsp of olive oil until crispy and golden. About 5 minutes a side.
Assemble the sandwich with the toasted English muffin, hash brown, cheesy patty, tempeh and drizzle on the spicy mayo. Dig in!
