vhdl code for bcd to decimal decoder

I think you mean a BCD-to-7-segment decoder.

Here is the 'case' statement from a digital clock project that I wrote some time ago. Maybe it will help you.

'nibble' is the 4-bit input code (similar to your BCD value), and 'segment' is an 8-bit register connected to the 7-segment display (and its unused decimal point). It displays hex digits 0 through F. For example, when nibble is 3, it illuminates segments a b c d g.
Code: 
    case (nibble)
       0: segment <= ~8'b11111100;  // "a b c d e f g h"
       1: segment <= ~8'b01100000;
       2: segment <= ~8'b11011010;  //   --a--
       3: segment <= ~8'b11110010;  //  |     |
       4: segment <= ~8'b01100110;  //  f     b
       5: segment <= ~8'b10110110;  //  |     |
       6: segment <= ~8'b10111110;  //   --g--
       7: segment <= ~8'b11100000;  //  |     |
       8: segment <= ~8'b11111110;  //  e     c
       9: segment <= ~8'b11100110;  //  |     |
      10: segment <= ~8'b11101110;  //   --d--  (h)
      11: segment <= ~8'b00111110;
      12: segment <= ~8'b10011100;
      13: segment <= ~8'b01111010;
      14: segment <= ~8'b10011110;
      15: segment <= ~8'b10001110;
      default: segment <= 8'bx;
    endcase
