It's probably easier to spot the WAP browser rather than the other way around. They send all sorts of goodies in their headers. The 'user-agent' header always contains the string "UP.Browser" so you could search for that. WAP browsers usually send the 'accept' header as well so you could use that to look for 'text/vnd.wap.wml'.
That's my opinion.
