I have the entrez IDs of a set of genes and I test these with a universe of entrez IDs in hyperGTest to get the significant KEGG and PFAM terms. Now, I want to know which particular entrez IDs in my set of genes map to a particular significant KEGG/PFAM ID.

Look at the org.Hs.eg.db package (for human).  There are mappings there.
