The man page does not document any "interfaces" directive. Rather, it 
says to include the names of interfaces on the command line.

Including em2.112 on the command line does not help. dhcpd still does 
not respond to dhcp requests on vlan 112.
How is including this command line supposed to tell dhcpd that the 
interface is tagged and to do anything different than when it 
auto-discovers the interface based on subnet declarations?

There is not default vlan. They are all tagged.
I'm not sure what you mean by "enable the vlans in the configs."
