Just create an MQTT Device and add a ‘Turned On/Off’ capability pointing to the correct state & command topics of your tasmota device.

Then you have two options to solve your problem:

1. Either configure the input and output templates like this:  
input: value == ‘on’  
output: value ? ‘on’ : ‘off’  

2. Or leave the input & output templates empty. After creating the device, go to the advanced device config and select ‘on/off’ for the ‘on/off values’ setting (true/false in screenshot), this will automatically convert boolean values to ‘on’ & ‘off’ in both directions.  

Marh.js expression examples can be found here:

You can use ‘path.to.property’ I stead of ‘value’ within the templates, if the input is a JSON formatted message.
