Any 26" tyre will be fine, as long as it
- Fits between your chainstays/seatstays/brakes/fork when mounted without rubbing
- isn't too small (or big) for your rim's internal width
- has exactly the same ETRTO diameter
Most of the versions of that bike seem to have a 2.1" width tyre, so its likely you'll be able to fit a 1.5" to 2.1" wide 26 inch tyre without issue. 26 inch is also known by the ETRTO size 559 or 559-widthinmm so yours probably have 559-53 or 53-559 on the sidewall.
Just to confuse things, there are <26"> tyres that have a different ETRTO code, or may be so old that they don't have such a code. You're not likely to find these on your bike, but you might find them for sale. The ETRTO codes could be "26 inch" are 559mm, 571mm, 584mm, 590mm or 597mm. You need to match whats on your existing tyres.
If you want thinner than 1.5" (or ~38mm) then you'll want to measure the inner valley width of the rim and compare it to the chart at What is the maximum or minimum tire width I can fit on my bicycle?
Remember to buy 3 new tubes as well, two for the bike and one in your bag as the spare.
My commuter bike is 26" wheel as well, and finding fast road-oriented tyres is challenging - the range is very small for sporty offerings, so you will probably be looking at commuter-tyres which tend to be more puncture resistant. Still much faster than using knobbly tyres on the road.
