Not gate with 3 LEDS attached after NPN transistor
Simplest way is to use a 1PDT push button..

Otherwise you probably need another transistor \$Q2\$ that is normally biased on and is turned off when the original one \$Q1\$ turns on.

You CAN tie \$Q1\$ to \$R2\$ via a diode \$D7\$, but then \$R2\$ needs to be 1/2W and \$Q1\$ needs to dump a lot more current than you need.
