Find some good interview books related to your skills/ role (from Amazon) (don't go for generic interview books but those specially designed for your role)
Get some good CV templates for people with same level and experience level ( you will find them in the above mentioned interview books...and also peep into some LinkedIn profiles to get some useful points that may not easily occur to you). Don't waste time on the final version. You will never get satisfied. Improving your CV is a continuous process, where you keep coming back and update/delete / customize your content.
Start applying in those companies that you will not join just for practice. REMEMBER ONE THING..Please don't get demotivated if first few interviewed are failure..You have been out of market for long, so you need practice...practice and practice to adapt...but this you have to do without taking the defeats to your heart.Just analyze what went wrong , prepare and attack again.
Read some good books /articles on body language (if possible record your mock interviews) and salary negotiations (specially since you would getting less than half of market , having worked in this labor camp for long)
Its human instinct to fear change....But not all changes are bad.
be positive all the time....
START NOW...If you don't take decisions on your life in time, then life may enforce decisions on you that you may not like.
