I have taken a break too and it was a good 4.5+ years.
This is how I mentally prepared myself. 'No matter what my skills are, there is a job for everyone in this world'. With that in my mind, I took concrete steps to get back in the industry.
I looked at my original skill set, looked at the documentation of each for the latest versions and spent enough time to understand the changes. YouTube videos, blogs, online tutorials helped me a lot. I practised a lot as well.
This have me a good idea of what I am yet to learn and what I already know. At the same time, there were new technologies that are vogue in the market. I got a glimpse of it by going through the above said sources. It did help me a lot about the new technological advancements in the industry.
Then comes the job hunt. Writing a good cover letter is crucial here. Mention the gap period and also how you have upgraded with the latest versions/technologies; the intention is to show to the potential employer that you are equally enthusiastic about learning new things as you were when you have entered the industry.
Also, I found myself a few jobs where I was asked to work on legacy projects which didn't need the latest versions.
Being patient is crucial here. There are quite a few similar questions asked here; go through each of it. It gives a lot of information. Good Luck.
