Taking Hacking will give you access to the AI Hacking talent, this will allow you to turn the Geth to your side for a short amount of time, giving you more tools in situations where you’re up against them (which is a lot in Mass Effect 1). Due to the Adept already having most of the useful Bonus Talents already in the main kit, there’s not too many choices that stand out so you’re looking at Hacking or Electronics as the main ones to carry over, with Electronics being the better choice.

Provided you’ve unlocked some of the Achievements/Trophies related to using the associated Talents on a previous file, you’ll gain the ability to assign a Bonus Talent to your Adept at the time of Character Creation. You might not get access to the talents themselves but you can still effectively use a Sniper or Assault Rifle for enemies at greater ranges. The one downside from the original version of Mass Effect 1, only having access to Pistols, is also remedied here with the new changes to the weapon system.
