1: Change the "listen-on" settings to bind to network interfaces:

-       listen-on port 53 { 127.0.0.1; };
-       listen-on-v6 port 53 { ::1; };
+       listen-on port 53 { any; };
+       listen-on-v6 port 53 { any; };

2: Allow external queries by removing the allow-query setting entirely:

-       allow-query     { localhost; };

3: Disallow recursion by removing recursion setting:

-       recursion yes;

4: Add your zones.

DNSSEC is slightly more involved, but basic setup should be basically 
the same as what you've been doing.
