It is reasonably common for people in reconstructionist religions to say that they have "religion with homework". Many people have extensive recommendations of books to read, primarily academic ones, in order to introduce the principles of the religion to others, and Kemetic recon is no exception.
My academically-oriented recommendations to start out with are:
Temple of the Cosmos, Jeremy Naydler
The Ancient Gods Speak: A Guide to Egyptian Religion, Donald B. Redford
Conceptions of God in Ancient Egypt: The One And the Many, Erik Hornung
Daily Life of the Egyptian Gods, Dmitri Meeks and Christine Favard-Meeks
Egyptian Religion, Siegfried Morenz
