There are many ways to describe this.
You might try something like this
----------------------------------------------------------
constant c_maxpower: integer := 5;                 -- just an example
signal Ns : integer range 0 to c_maxpower;
signal N  : std_logic_vector(c_maxpower downto 0); -- left is c_maxpower 
                                                   -- or something bigger

p_power : process (Ns) is
  begin  -- process p_power
    for i in N(N'left) to N(N'right) loop
      if i = Ns then
        N(i) <= '1';
      else
        N(i) <= '0';
      end if;
    end loop;  -- i
end process p_power;
------------------------------------------------

Hope this helps.
