The latest issue of CGW (Computer Graphics World) has a nice article about the FX of The Mummy Returns. Fortunately it has been put online, with several color pictures and including some work in progress shots of Imhotep.
The article covers most of the major FX duties for the film, from Imhotep, warrior mummies and the pygmy mummies, to the water face, the use of mocap, the giant armies, and the oasis. Here is the link to the printer format page:
