(assuming the .mod and the .out name are always the same)

awk -v sq="'" -v dq='"' -F '[/.]' '{
       print "printf "sq"%s"sq" "dq"  "$(NF-1)" & "dq" >> TABLE.TEX";
       print}' yourscript.sh

All the commands are tested with bash and GNU tools, so they may use
nonstandard features. I try to mention when something is nonstandard (if
I'm aware of that), but I may miss something. Corrections are welcome.
