Outside a process you can write : 


WITH c SELECT
    HEX <= "01110110" when "000",
               "01111001" when "001",
              ....
               "00000000" when others;



WITH c SELECT
    HEX <= x"76" when "000",
               x"79" when "001",
              ....
               x"00" when others;

But be aware that you are writing a MUX. It produces glitches.
