Contact the US Embassy and request a Transportation Letter. Don't take any risk. They won't let your wife get into the country without this letter. Good Luck!
A Transportation Letter is for people whose green card was lost or stolen during a short trip abroad.

This does not apply to zumier's wife. She does need a returning resident SB-1 visa.
A friend of my brother recently got stuck in Brazil when his green card got stolen at the very end of his 1-year stay there, just when he was about to return to the U.S. By the time he went to the U.S. consulate, a little more than a year from his departure from the U.S. has passed, and they made him apply for an SB-1 visa. As far as I know, it took him several months to get an SB-1 visa there, even though he is a German citizen and his wife and kids are U.S. citizens.

Our family has been residing overseas since my company sent me here in the summer of 2002. My wife has a GC and an expired (Jan 2006) re-entry permit and I and our 2 kids are US citizens. We're not living in my wife's home country. Our last trip to the States was 14 months ago. Now we want to go back for Christmas. What are our chances if we show up at the port of entry without an SB-1? 50/50? Anything we can do to improve our chances?
I think the chances of getting in without an SB-1 visa are pretty slim (certainly much smaller than 50/50). This is a clear-cut case of not satisfying the documentary requirements for a re-entry (either an SB-1 visa or a valid reentry permit, for absences over a year).
I think getting an SB-1 visa approved will not be easy in this case, since your wife has resided and worked abroad for 4 years. That is a pretty long time. Still it is worth a try.
Another option would be for her to start a GC process from scratch. Since you are a U.S. citizen, you can file a new I-130 petition for her and request consular processing. Then, at the end of the process your wife would get a new immigrant visa. This would probably only work if you and your wife actually intend to return to the U.S. now and stay there for good (rather than continue to live and work abroad).
The last option is for your wife to try to come for a short visit to the U.S. on a non-immigrant visa, e.g. a tourist visa. This would have the effect of your wife formally giving up her LPR status (and she might be required to submit a form relinquishing her LPR status first). Moreover, it would probably be hard to actually obtain such a visa, which requires proving a non-immigrant intent, since you are a U.S. citizen and your wife did have a GC in the past. But if your wife is from one of the visa waiver countries, she may be able to get in the U.S. in a non-immigrant status that way.
