Soak rice noodles in hot water for 8-10 minutes until tender, then drain and set aside.
In a small bowl, whisk together tamari, lime juice, sambal oelek, garlic powder, and ginger powder to create the sauce.
Heat sesame oil in a large skillet or wok over medium-high heat.
Add shrimp to the skillet and cook for 2-3 minutes until pink and opaque.
Push shrimp to the side of the pan, crack the egg into the center, and scramble until just set.
Add the drained noodles and the prepared sauce to the pan, tossing everything together to coat evenly.
Fold in the bean sprouts and scallions, cooking for an additional minute until the sprouts are slightly softened but still crisp.
Garnish with fresh cilantro and serve immediately.
