4 inputs = 16 states. I would use the raw Gray code as an index into a 16 character array of segment patterns. No other fancy translation required.

Like @crutschow says except sort the table on the raw gray code value so that it provides a direct index into the segment patterns for each digit.
The PDF shows how I would do it - a Gray to 7 segment decoder.
