What do I need?

I'm running a 1.5-3V motor... however, when the relay
switches, it creates a dip in RPM for a ms or two before jumping
back to full power.
What could I do to negate this blip in revolution? Could I use a capacitor
across the motor's leads as a sort of backup battery to tide
over the drop in current? And if so, what capacity would
I use?
Thanks.

Most likely the current draw is causing it.
Simply calculate the minimum capacitance you need to supply and throw in a cap with a slightly higher capacity to compensate for a possible higher or longer load.
Of course you need to specify your power supply (what kind of batteries), your motor's specifications, and your device hardware for anyone to be able to figure that out.
I'm using a 2300mAh 1.2 NiMh battery. I use a rechargeable
to save money so it's not the 1.5V recommend for the
motor 1.5V.
