Depends on what kind of toy photos you want to make. If you were doing the "here's what they look like/here's what's in the package/here's the scale" then you want a plain white bkgd, and as few visual distractions as possible. Just a white foam board will do.
If you wanted a diorama-style photo, then you can download backgrounds from the Internet, and glue it on white foam board. Ground/flooring can be Home Depot vinyl flooring samples, or Spanish moss glued on MDF, or tiles/bricks made from scrapbook paper, or cardboard, or egg cartons. Load the diorama up with various accessories, too.
For dioramas, cropping is, of course most important. You need to hide all the setup stuff so your audience imagines the toy world as "reality".
