The Egg Store (google it) has powdered whole egg, so does Adventure Foods (look under bulk foods.)

Powdered eggs can be made to a near-fresh consistency.  The key is to add water to the powder in tiny increments and working the powder into a lump-free paste, a fork works well for this part.  Once a paste, add water in small amounts followed by thorough mixing (here you can use a spoon) until it reaches the consistency of well-beaten raw eggs.

This is the best you can get with powdered eggs.  Fools would fry it up without some sort of other ingredients.  Rehydrated veggies like dried peppers, onions, freeze-dried mushrooms, along with bacon and lots and lots of cheese surely help improve the blandness of the powdered eggs.
