Drain tofu, then pat dry with a towel. Slice into 3 rectangle slabs.
Mix 1 tablespoon soy sauce and kelp powder in a pan (big enough to fit all the tofu).
Marinate tofu for 15 minutes (rubbing the surface with the marinade).
To make the sauce, combine mirin, hot water with kelp powder, soy sauce, maple syrup and sugar in a bowl. Stir to combine.
To create a spicy mayo, mix together vegan mayo and chili sauce until incorporated.
Next, heat a large non-stick skillet over medium heat. Add about a tablespoon of oil. Carefully slide marinated tofu onto the hot pan. Cook in batches if needed, adding more when necessary.
Pan-fry until tofu is golden brown (the larger surface). Add 2-3 spoons of sauce. Gently push the tofu around the pan so it catches all the sauce.
Meanwhile, place a nori strip on a plate. Lay the cooked slab on top and fold the nori needs over.
Place cooked rice in a bowl and sprinkle with furikake. Next, top with vegan salmon, drizzle with spicy mayo, and top with a handful of vegan cheese. Using a hand torch, melt the cheese and garnish with chopped scalions. Serve warm.
