The code logic and structure by itself is the same so, you can almost just take each line and change it to it's VHDL equivalent. Why don't you try it and show us what you wrote, if you have more questions? It is really basic VHDL.

The only big difference in VHDL is that you will have to put everything in a process, and specify that you want it executed on the rising edge of clk.
