The serial number is not broadcast. You will be unable to track with that method. The only way is if you had some sort of program on it that would allow for tracking.
Also, the MAC address is not tied to the serial number and not broadcast past the ISP, so would not be of help.http://www.ehow.com/how_4586129_track-laptops-_mac-ip-address.html
You are probably screwed.
