Whisk together all ingredients for the mushroom marinade.
Add the sliced shiitake mushrooms to a shallow bowl and pour the sauce on top. Toss around until each piece is well coated.
Set aside and preheat the oven to 400 degrees Fahrenheit.
While the mushrooms are marinating, add the finely minced garlic and chopped scallions to a large pot with the oil. Saute for about 2 minutes or until the garlic starts to brown.
Whisk in the soy sauce, miso paste, maple syrup and sriracha if using. Pour in the vegetable broth and stir everything together.
Let simmer for about 20 minutes to allow all of the flavors to absorb together.
Meanwhile, add the mushrooms to a baking sheet lined with parchment paper and bake for 25-30 minutes.
During the final 10 minutes, remove the tofu from the package, drain off excess liquid and cut into 1 inch cubes.
Add to a pan with the toasted sesame oil and saute for 3-5 minutes on each side or until crispy. Toss with soy sauce.
Add the ramen noodles to the pot with the broth and cook for about 3 minutes. Taste and adjust flavors as desired. If you used low sodium veggie broth you may want to add a touch more salt.
Remove the mushrooms from the oven and assemble your bowls with the soup, tofu, mushrooms and top with chopped kale/spinach and finely minced cilantro and scallions. Enjoy!
