Hi Sam, like everything we on a boat, planning and preparation is the key.
Here are some ideas:
1. While beating note the direction the boat is travelling, then practice visualizing an imaginary line at right angle to the center line of the boat (Extend the bulkhead line at the companionway or the stern of the boat, whatever is easier) take note where it is pointing on the windward side, this will be roughly the new direction of travel after the tack. Pick a visual mark on that line, this where you will point after the tack.
2. Practice giving instructions (even to yourself) by saying "Ready to Tack" or "Ready About". This is a reminder to make sure the cockpit is clear and all sheets are ready to release and can be pulled in. Move obstacles out of the way.
3. When ready to tack, again give instructions "Tacking" or "Going About". don't worry how it sounds it really works, even the pros do it. Now just concentrate on the new direction established 1. above, and concentrate on the sheets running correctly.
4. Don't rush, turn the boat positively through the wind, releasing the holding sheet and take up pressure on the new sheet, continue the turn pulling on the sheet trying to minimise flapping of the jib, move smartly and positively.
5. Try not to turn beyond the imaginary line established in 1, above. and secure the sheet.
As the boat settles on the new tack adjust the sheet to the correct tension.
The main will have looked after itself.
Here is an example of solo tacking in confined channel with a strong breeze on the nose.
Hope this is of some help.
