There is no way to "detect" a spoofed MAC address.
There ought to be limits to freedom. - George W. Bush

There is danger from all men. The only maxim of a free government ought to be to trust no man living with power to endanger the public liberty. - John Adams

They who would give up an essential liberty for temporary security, deserve neither liberty or security. - Benjamin Franklin

If someone wants to break your wep, consider it broken. Readily available free software can crack WEP in a matter of minutes. Wireless packet sniffers can then detect MAC addresses and that's all she wrote. WEP by itself my keep random lazy people from latching on to your network, but it will not hold up to a determined entry.

In fact, The FBI demonstrated publicly (that looks spelled wrong...) today that they can break a 128bit WEP key in under 3 minutes using simple tools found commonly on the web.

Just wait til someone releases an all-in-wonder program for the script kidddies. No one will be safe.

There are ways to detect MAC spoofing, promiscuous mode, IP spoofing, and other questionable pratices but, like what others have stated, do not depend on WEP to keep yourself secure. See one of my earlier posts describing one way secure a wireless network.
