I have a Canon 60D, bought it back in 2013. Use it quite a while, but in past two-three years, I lost interest in photography. I will be going on a long trip this summer and would like to take a decent camera with me. Is Canon 60D still a decent one or I will be missing on features and upgrades comparing to the latest versions?
In terms of lenses I own Tamron 24-70 2.8 And Canon 100 2.8 Macro.

It's a decent camera, even today. If you've 'lost interest' spending money is something you have to decide for yourself.
Take the camera and your lenses, possibly see if somewhere will rent a lens for a vacation or use the Internet to research somewhere to rent lenses at your destination (and read their Fine Print).
Bring your phone, a backup camera (and portable telephone) is handy while traveling.
... or I will be missing on features and upgrades comparing to the latest versions?
Yes, you're missing a bit. You can find out what by using 'Online Comparison Tools':
Once you determine what you're missing (not an awful lot) you can use the link suggested by @scottbb When should I upgrade my camera body? to decide if it's "worth it" - I opine no.
Since you have so few lenses another choice is to get out of Canon's two digit lineup and look elsewhere. If saving size and weight is your primary consideration then mirrorless is another option.
They make some compact mirrorless cameras like the M100, you should examine why you became disinterested and seek to fix that - without spending a lot of money.

See prior advice about renting, if it's an expensive trip (far away) a bunch of great (and different focal length) photos makes financial sense; to record your memories and increase the value of trip.
Spending money sounds like an easy fix, the question is: will it fix the problem?
It's as good a camera now as it was then. Unless you understand what about the 60D is limiting your photography, then the right option is not to spend money. You'll almost certainly get more value out of either a wide angle or telephoto lens - you can pick up either the EF-S 10-18 or EF-S 55-250 for a lot less than a new body (or both for still a lot less than an 80D), and both will give you whole new possibilities when travelling, as opposed to the incremental improvement you get from a new body.
The 60D is still a great, capable camera. My Nikon D5000 that I use as an extra body is still great, despite it being from 2009. As others have said, you will definitely benefit from new lenses, though. The problem is that if your vacation is long and you will be walking/hiking a lot, carrying around a big heavy DSLR can (and most likely will) be tiring. You can always rent out a nice mirrorless camera (or even buy one) for hiking and use the 60D for everything else. Also, one thing to keep in mind is that the camera is nothing, the person behind the camera is everything!
Edit: to talk more about cameras and less about lenses.
