Cook the soba noodles in boiling water according to package directions, then drain and set aside.
Press the extra firm tofu to remove excess moisture and cut it into 1-inch cubes.
Heat the avocado oil in a large wok or skillet over medium-high heat.
Add the tofu cubes to the wok and sear until they are golden brown and crispy on all sides.
Add the minced garlic and grated ginger to the pan, sautéing for 30 seconds until aromatic.
Toss in the shredded cabbage, sliced bell peppers, and shelled edamame, cooking for 3-4 minutes until the vegetables are tender-crisp.
Sprinkle the curry powder, garam masala, turmeric, sea salt, and black pepper evenly over the vegetable and tofu mixture.
Add the cooked soba noodles, tamari, and nutritional yeast to the wok.
Toss everything together for 2 minutes over high heat until the noodles are well-coated and the flavors are fully integrated.
