Since youve got the MOSFETS heres how to connect them to the relay coils but 2 resistors are needed.

Starting at the Relay Coil. Connect one end to Battery +ve the other end to MOSFET drain. Connected MOSFET source to Ground.
Connect one 100k (ish) resistor from MOSFET Gate to MOSFET Source (Ground). This keeps the mosfet off when no voltage on Gate is present.
Connect the other resistor at least 10 times less than other resistor (eg 10k) to the gate and the other end to the input signal 0V = Relay off & 10-15V = relay on (Maybe 5V if logic MOSFET).

You can uses the same circuit for NPN but use lower resistors depending on gain of transistor but 1k & 10k will be typical and will turn on with more than 1V input and Gate = base, Source = emitter, Drain = collector.
