There is a process to replace a lost/stolen permanant resident card...link below.

However, you have some serious circumstances that may make that mute. If the conditional was for two years and expired, then she probably is considered to have abandoned the LPR status. It is quite possible you might have to go through the process again from the beginning. With no valid form of government ID, this is going to be difficult.
I would Highly recommend a lawyer to help because she has no status and no valid form of ID.. I would also suggest she contact her home country embassy/consulate here in the US to see how she can get a valid passport
