7 bit in 2 seven segments

I think you first have to convert a binary natural number into BCD and then instance two times decodificador, one for the units digit and one for the tens.

Remember that 33 in decimal needs 8 bit in BCD (0011 0011) so your convertion module is charge to generate BCD code for units and BCD code for tens.

for example:

process(...)

.......

if(bin>=10 and bin<20) then bcd_tens<="0001"

........

for the units i think you should be able to drive the related decodificator with (bin mod 10) that should be the BCD units by itself.....
