If you're looking for a crampon for general mountaineering purposes, take a look at these options. Those are 'strap on' style crampons that basically fit on any kind of boot. Looking at your particular snowboard boots, you would not be able to use a 'step in' style or 'hybrid style' crampon, as your boots do not have a heel or toe welt to accept the bales on those style crampons. For more information on crampons, check out this Expert Advice article on How to Choose Crampons.
Depending on the size of the boots you wear, you may need to get a 'long bar' to accommodate your boots. Generally, crampons fit up to a size 12 boot so if you're at or above that size you'll likely need a longer bar, particularly given the extra bulk you get with snowboard boots.
Hope this helps!
