Stir in the vegetable broth, soy sauce or tamari and thyme, and stir to combine. Reduce heat to medium-low and simmer until the liquid has reduced by a third, about 10 minutes. Mix in the Vegan Sour Cream and flour. Continue to simmer until the sauce thickens, another 3 minutes. Remove from heat.
Cook the pasta according to package directions, until al dente. Drain, rinse and return the noodles to the pot. Pour the mushroom sauce over the pasta and stir to coat.
