There is no set response to be made to many greetings. Just reply in a suitable manner with whatever phrase makes sense.

Take good care
could have any of the following responses -- and these are just a few examples. Others are also possible:
I will
Thank you
You too

Look forward to hearing from you (Note the correction to your sentence) could have any of the following responses. Again, there are many other possibilities:
You too
I'll be in touch
I'll speak to you soon
I'll get back to you as soon as possible

There is no such word as 'alot' in standard English. You need to write 'a lot'.
