Your brief description of the operation of your OCXO sounds like a
typical OCXO - higher current at start up til stabilization, then lower
current draw. Same goes for the frequency drift.
The adjustment only needs a potentiometer to be used as a voltage divider
and is not overly critical as far as value is concerned. I tend to use
something around 5k.
There is often a Vref output from OCXO that you would use on one side of
the pot rather than the VCC, the other side of the pot to ground, and
the wiper to the ADJ.
Don't expect a lot of adjustment range, on the order of single digit Hz
+/- of the nominal frequency
