This is my email_template.html

 <table class="order-details">
 <tr>
 <td class="address-details">
 <h3>trans "Billing Info"</h3>
 <p>var formattedBillingAddress</p>
 </td>
 depend order.getIsNotVirtual()
 <td class="address-details">
 <h3>trans "Shipping Info"</h3>
 <p>raw</p>
 </td>
 /depend
 </tr>
</table>

and in my observer

$templateVars = array(
 'store' => $this->storeManager->getStore(),
 'message' => 'We processed your order ID We will contact you soon in mail for the acknowledgement if you not receive mail within 4 hours please get help from support@xxx.com',
 'order' => $order,
 'store'=> $store,
 'productName'=> $productName
 );

->setTemplateVars($templateVars)

My question is how can i set values of billing info, shipping info and payment method in this email template.

Inject class Renderer used for formatting an order address and some classes for Payment into your constructor.

/**
 * @var MagentoSalesModelOrderAddressRenderer
 */
protected $addressRenderer;

 /**
 * @var MagentoPaymentHelperPaymentHelper
 */
protected $paymentHelper;

public function __construct(
 MagentoSalesModelOrderAddressRenderer $addressRenderer,
 MagentoPaymentHelperPaymentHelper $paymentHelper
) 
 $this->addressRenderer = $addressRenderer;
 $this->paymentHelper = $paymentHelper;

Add to $templateVars:

$templateVars = array(
 'store' => $this->storeManager->getStore(),
 'message' => 'We processed your order ID We will contact you soon in mail for the acknowledgement if you not receive mail within 4 hours please get help from support@xxx.com',
 'order' => $order,
 'store'=> $store,
 'productName'=> $productName,
 'payment_html' => $this->getPaymentHtml($order),
 'formattedShippingAddress' => $this->getFormattedShippingAddress($order),
 'formattedBillingAddress' => $this->getFormattedBillingAddress($order),
 );

Build the methodes for shippping , billing address and payment:

/**
 * @param Order $order
 * @return string|null
 */
protected function getFormattedShippingAddress($order)

 return $order->getIsVirtual()
 ? null
 : $this->addressRenderer->format($order->getShippingAddress(), 'html');


/**
 * @param Order $order
 * @return string|null
 */
protected function getFormattedBillingAddress($order)

 return $this->addressRenderer->format($order->getBillingAddress(), 'html');


/**
 * Get payment info block as html
 *
 * @param Order $order
 * @return string
 */
protected function getPaymentHtml(Order $order)

 return $this->paymentHelper->getInfoBlockHtml(
 $order->getPayment(),
 $this->identityContainer->getStore()->getStoreId()
 );

See a good sample here:

vendor/magento/module-sales/Model/Order/Email/Sender/OrderSender.php
vendor/magento/module-sales/view/frontend/email/order_new.html

$templateVars = array(
 'store' => $this->storeManager->getStore(),
 'message' => 'We processed your order ID We will contact you soon in mail for the acknowledgement if you not receive mail within 4 hours please get help from support@xxx.com',
 'order' => $order,
 'store'=> $store,
 'productName'=> $productName
 );

you can use the above variable in email templates like

for write static text you can use -> trans "Dear"

for include variable you can use -> var productName

for example you greet your customer in mail templates like

<h1 style="font-size:22px;font-weight:normal;line-height:22px;margin:0 0 11px 0;">trans "Dear " var customer_name,</h1>

In this above example customer name is the $templateVars array index. You need to get customer name from observer after that you can pass that value into $templateVars array.

For magento 2.3, replace this

MagentoPaymentHelperPaymentHelper $paymentHelper

with

MagentoPaymentHelperData $paymentHelper
