Worried about protein and nutrients

Does anyone know how much protein you should have per day???? I have been eating a vegan diet for a couple of weeks straight now and I'm feeling really great but I know I'm not eating very much protein. Does anyone have simple high protein vegan recipes (wow that was specific). I don't know how credible this particular source is but I have been finding a lot of article along the same lines as this one http://chetday.com/strictvegandiet.htm. I have also found articles opposite on websites that promote veganism, so thats kind of biased. Has anyone found any clinical evidence that veganism can cause nutritional deficiencies???

Tried Skinny Bitch Recipe

"Chicken" Noodle Soup

What you need

1 tablespoon refined coconut oil
1 carrot, halved lengthwise and cut into 1/4-inch slices
1 celery stalk, cut into 1/4-inch slices
1/2 onion, cut into 1/2-inch dice4 ounces
white or cremini mushrooms, cut into 1/4-inch slices
1 teaspoon fine sea salt
1/2 teaspoon pepper
1/4 teaspoon curry powder
1 bay leaf
8 cups vegan "chicken" stock (hot water mixed with vegan bouillon according to package directions)
2 teaspoons Bragg's Liquid Aminos (or 1 1/4 teaspoons tamari or soy sauce)
8 ounces vegan "chicken" strips or chunks (if frozen, no need to thaw)
4 ounces whole wheat or brown rice pasta

What you do

Heat the coconut oil in a four-to six-quart stockpot over medium heat. Add the carrot, celery and onion and cook, stirring occasionally, until crisp tender -- about two minutes. Add the mushrooms, salt, pepper and curry powder and cook until the mushrooms release their juices -- about two minutes. Stir in the stock, Bragg's Liquid Aminos and bay leaf. Increase the heat to high and bring to a boil. Add the vegan chicken and pasta. When the soup returns to a boil, reduce to a simmer. Cook until the pasta is tender.

This was a pretty good alternative to actual chicken soup, and clearly more healthy. I didn't go with all the ingredients exactly because I didn't have everything. I didn't use the bay leaf, my vegan chunks were tofu, and instead of coconut oil I used olive oil. Oh yea and I don't even know what liquid braggs aminos or cremini mushrooms are! lol.

I used to make chicken noodle soup a lot during the cooler whether and I used rice instead of pasta. I might try rice with this recipe instead of the pasta next time.
