Wiring 2-way connected switch in 2-gang configuration
The black coming in to the double loaded screw is the always hot. It is then jumpered over to the other switch. Each then has a switched how leaving to the lights.

you can make this proper by using another short black wire and wirenutting it along with the existing jumper wire and the always hot. Then every screw in the switch will have exactly 1 wire connecting it as is proper. 

As for the neutral you can add a white wire to the wirenut to jump it over to the smart switch (though you may need to get a larger size nut).
