Mezcal is a Mexican agave spirit with its own denomination of origin, made from dozens of agave species. In traditional styles the hearts are roasted in earth-and-stone pits before fermenting, and that is where the smoke comes from.
Where mezcal shares the base with tequila, simply replace its share with more tequila.
This is the nearest swap, in the same amount. The agave stays, though the smoke goes.
Tequila and peated Scotch
To bring some smoke back, replace a barspoon of the tequila with peated Scotch. The smoke will be peat rather than roasted agave.
"Mezcal is smoky tequila"
Cousins, not versions of each other: they differ in agave, cooking and rules, and smoke is only the most obvious difference.
