First time solo traveler need essential list

I traveled out of country many times but this time I want to spend a month traveling south east Asia , India , and Egypt or Tunisia , haven’t made a exact itinerary or anything but what’s some good essentials that aren’t just the basics and should I bring a back packing bag over a rolling suit case ?
