If you look for physical or chemical evidence that the catalyst indeed participates in the reaction, there are many things you can do. Some are easy but some requires equipment (even very advanced equipment). To discuss further, give me your reaction.
If you just want to tell a catalyst in a chemical reaction equation, it is usually written above the equal or arrow sign.

Well, if you know how much reactants you used and know how much product you can collect afterwards you will know if you used a catalyst or not. For example, if you know you used 5,00g of A and 10,00g of B and you also know that you get 3,00g of a gas c and 12,00g of a solid D, then, you are expected to recover 12,00g of the solid (since the gas flu away). If you collect 16,00g of solid, well, then a catalyst had to be present (catalysts can be always recovered after the wanted reaction happened).

A catalyst is never destroyed during a reaction. It should be present before and after.

the c atalyst will be written over the equal sign in teh reaction
