Heat 1 tablespoon oil in pan over medium heat. Add onions, bell pepper, jalapeno, hefty pinch of salt and pepper, and sauté until veggies are tender, about 5 minutes. Add garlic, cumin, smoked paprika, oregano, liquid smoke, and corn. Stir to combine and heat through. Remove from pan and set aside.
Heat another tablespoon oil in same pan. Add vegan sausage, break apart to crumble and cook until browned. Return the veggies to the same pan with sausage and stir to combine. Remove from heat and stir in cream cheese and spinach and stir so spinach wilts a bit.
Spray baking dish with non-stick spray. Spread sausage/veggie mixture in baking dish. Pour vegan eggs over mixture. Top with tater tots to cover.
Bake 375 degrees, uncovered, for about 40 minutes until the vegan eggs are set and tater tots are crispy. Remove from oven, let sit for about 10 minutes, top with chopped cilantro, avocado sauce (or diced avocado), diced tomatoes (or Pico de Gallo), if using, and serve with lime wedge.
You can make this ahead of time and store in refrigerator, covered, until ready to bake.
