Open your web browser and go to:
http://192.168.1.1 (or whatever the address to your router is)
When you have logged in click on the STATUS tab.
Click on the DHCP Clients button. Now, every machine attached to the network along with their MAC address will be displayed. If there are more machines than you have that are attached, you have an intruder.

Well unfortunately you can't with out some software to detect them. You can indeed check your router for all the DHCP connections but if someone has set an IP outside of the "pool" your router (most routers) wont show those connections.
Some internet suites (trend micro etc) have a wireless monitor that will show all ips that are in use. Those will detect "invaders". Or you can get some ip monitoring tools that will scan your network for all IP's that are in use.
Best bet is to SECURE your wireless network with the security tools provided with your router. WEP is minimal and can be "cracked" so if you have other choices use them.
You can also authorize only the "MAC" addresses of the units that are supposed to be connected.
