Soak the brown rice noodles in hot water according to package directions until al dente, then drain and set aside.
In a small bowl, whisk together the tamari, sesame oil, lime juice, maple syrup, and red pepper flakes to create the pad thai sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat and sauté the minced garlic for 30 seconds until fragrant.
Add the shrimp and cubed tofu to the skillet, cooking for 2-3 minutes until the shrimp is pink and the tofu is lightly golden.
Push the shrimp and tofu to one side of the pan, crack the egg into the empty space, and scramble until just set.
Add the drained noodles and the prepared sauce to the skillet, tossing everything together for 1-2 minutes until the noodles are well-coated.
Fold in the bean sprouts and sliced green onions, then remove from heat.
Serve immediately topped with crushed peanuts and a fresh lime wedge.
