I assume that you are a U.S. citizen. If so, then all your wife needs to prove her eligibility for adjustment of status is that she were inspected and admitted into the U.S. Normally a stamp in her passport showing that she was admitted to the U.S. is sufficient to satisfy this requirement. Therefore she should be able to submit a copy of her passport in lieu of her I-94. At the same time she should apply for a replacement of her I-94.
Form I-102 can be filed along with I-130/ I-485. This is assuming you are USC applying for spouse who entered with inspection.
