Paprika is made from bell or chili peppers that have been finely ground two or more times without the veins and seeds, according to Katherine K. Schlosser, author of The Herb Society of America's Essential Guide to Growing and Cooking with Herbs. Because of that, you can swap sweet paprika for another pepper-based spice, such as cayenne or chili powder. Like using other types of paprika, these spices will lend your recipe a different flavor than you would get from the sweet paprika.

To create the same flavor as smoked paprika using the suggestions above will be your best bet. But if you want to add some heat that can be found in hot smoked paprika, use any of the substitutes above paired with hot red pepper flakes.

Spicy ketchup will obviously be sweeter and very mild in comparison to Sriracha, so as an ingredient, it’s good for big proportions (like for meatloaf). We wouldn’t use it for more authentic chili sauce needs (go with Sriracha there), but based on your recipe context, it can work.
