Modeling transformers in SPICE requires some specialized knowledge. SPICE represents a transformer as inductors ("L"elements) with mutual inductance coupling ("K" elements). The "catalog" specs typically do not include the necessary information to formulate such a model, so measurement or informed guesswork is required. Probably the easiest solution is to use a AC independent source (vac-1.sym in gschem) to drive the rectifier, and forget about modeling the transformer.
