Heat 1 tablespoon of sesame oil in a large skillet or wok over medium-high heat.
Cut the smoked tofu into bite-sized cubes and add them to the hot pan. Cook for 6 to 8 minutes, turning occasionally, until golden brown on all sides. Remove the tofu and set aside.
Cook the Lotus Foods ramen noodles or vermicelli according to the package directions. Drain well and set aside.
In a medium bowl, whisk together the vegan oyster sauce, tamari, sesame oil, maple syrup, rice vinegar, vegetable stock paste, and water until smooth.
Prepare all of the vegetables by shredding the napa cabbage and carrot, slicing the bell pepper and green onions, mincing the garlic, and chopping the basil.
Heat the remaining 2 tablespoons of sesame oil in a large wok or skillet over medium-high heat.
Add the garlic, napa cabbage, edamame, bell pepper, carrot, and green onions. Stir-fry for about 8 to 10 minutes until the vegetables are tender-crisp and lightly caramelized.
Return the smoked tofu to the pan.
Pour the prepared sauce over the vegetables and tofu, stirring until everything is evenly coated.
Add the cooked ramen noodles and gently toss everything together.
Continue cooking for another 3 to 5 minutes until the sauce thickens slightly and coats the noodles.
Remove from the heat and garnish generously with fresh chopped basil before serving.
