You really should have a VHDL tutorial or text book to get some ideas for trial and error. And furthermore learn about the basic concepts of the language and HDL programming in general.

For compatible types, e.g. bit vectors of same length, a typecast is simple. You already have one in your code 

q <= std_logic_vector (count_sig);

Trial and error actually has a good chance for a hit with the opposite direction 

count_sig <= unsigned(p);
