Unless you have the unlikely capability of coupling your smart card with a GSM chip or signal transmitter for use with the Global Positioning System (GPS) satellite network -- which is possible if you are using a mobile two-factor authentication scheme, I'm afraid there's really no way to track it down.
Assuming you've developed and distributed a corporate policy concerning the appropriate use of smart cards and/or other access devices to support your actions should this become a legal matter, you should have disabled the smart card, which is the reasonably expected action.
